mobile-testing-detox is a skill for Claude Code, Codex from agents-inc/skills. It costs 38 tokens per session (4,245 once invoked), scanned A, original, MIT.

A Detox framework for end-to-end testing of React Native apps, with automatic synchronization between JavaScript, native screens, and network activity.

In plain words
What is it for?
Use it to test taps, text entry, visible states, waiting behavior, device actions, mocks, test artifacts, and continuous-integration runs.
Why use it?
It reduces flaky tests caused by timing problems and provides stable ways to find, operate, and check mobile interface elements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mobile-testing-detox scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Detox E2E Testing Patterns

Quick Guide: Detox is a gray-box E2E testing framework for React Native. It synchronizes with the app's JS thread, native UI, and network automatically -- eliminating flaky sleep() calls. Match elements with by.id() (preferred), act with .tap() / .typeText(), assert with expect().toBeVisible(). Use waitFor().withTimeout() only when automatic sync fails. Always add testID to interactive elements and forward it to native components. Mocking happens via Metro source extensions, not Jest mocks.


<critical_requirements>

CRITICAL: Before Using This Skill

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

(You MUST add testID props to every interactive element and forward them to native components -- Detox cannot find custom components without forwarded testID)

(You MUST use by.id() as the primary matcher -- it is locale-agnostic, stable across UI changes, and decoupled from display text)

(You MUST call waitFor().withTimeout() only as a last resort -- Detox auto-synchronizes with JS, UI, and network by default)

(You MUST use Metro source extensions (.mock.js / .e2e.js) for mocking -- Jest mocks do not work in Detox E2E tests)

(You MUST set a withTimeout() on every waitFor call -- calling waitFor without a timeout does nothing)

</critical_requirements>


Auto-detection: Detox, detox, .detoxrc.js, detox.config.js, by.id, by.text, by.label, element(), expect(), waitFor, device.launchApp, device.reloadReactNative, device.terminateApp, device.disableSynchronization, testID, E2E test React Native, gray-box testing, detox test, detox build

When to use:

  • Writing end-to-end tests for React Native apps on iOS and Android
  • Configuring Detox device, app, and artifact settings in .detoxrc.js
  • Matching elements, performing actions, and asserting expectations
  • Handling synchronization issues with animations or long-polling
  • Mocking network responses or app configuration for E2E tests
  • Setting up CI pipelines for automated Detox test runs
  • Debugging flaky tests caused by synchronization problems

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
